Breast cancer remains a major global health challenge, with treatment effectiveness often limited by drug resistance and the toxic side effects of chemotherapy on normal cells. The exploration of bioactive compounds from natural sources through a medicinal chemistry approach offers a promising alternative strategy. This study aims to examine the molecular mechanisms of action and Structure-Activity Relationships (SAR) of various natural compound scaffolds as potential breast anticancer agents. The method employed was a systematic narrative literature review of 15 recent scientific articles evaluating computational parameters, including molecular docking, as well as in vitro and in vivo activities. The results indicate that polyphenols, flavonoids such as quercetin and EGCG, and curcumin possess strong cytotoxic activity and high binding affinity toward cancer-related target macromolecules. SAR analysis demonstrates that key structural features, including the number and position of free phenolic hydroxyl groups, the presence of gallate ester groups, and conjugated diketone systems, play a crucial role in determining ligand receptor complex stability. These interactions are supported by hydrogen bonding, hydrophobic interactions, and favorable steric compatibility within receptor binding sites. Computational findings further suggest that structural optimization can enhance ligand selectivity and improve pharmacokinetic properties. This study concludes that natural phytochemical scaffolds have significant potential as lead compounds and provide a rational basis for Computer-Aided Drug Design in developing more potent, selective, multi-target, and safer breast anticancer therapies.

The method used was a quasi-experiment with a pre-test and post-test design involving 20 respondents who were parents of U-13 athletes. Education was provided in the form of direct counseling sessions and group discussions, which were supplemented with supporting materials such as leaflets. The Wilcoxon signed rank test was used to analyze changes in parental knowledge and attitude scores before and after the intervention. The results of the analysis showed a significant increase in parents' understanding and positive attitudes towards balanced nutrition after education (p < 0.05). The results showed a significant increase in the level of parents' understanding and positive attitudes towards nutrition after the education intervention. These findings highlight the importance of active parental involvement in ensuring that young athletes' nutritional needs are met, as well as providing a basis for developing nutrition education programs in other sports schools.

This article examines the urgency of strengthening Islamic creed (aqidah) as a preventive instrument in addressing religious radicalism. The rise of extremism is not merely driven by sociological factors, but is also rooted in a theological crisis, namely textual interpretations that give rise to exclusivism and takfiri doctrines. Employing a conceptual literature review method, this study deconstructs the pathology of radicalism and reconstructs the preventive dimensions of aqidah. The findings reveal that ideological mitigation is grounded in three dimensions of aqidah: Tawhid as a means of liberating reason from group arrogance, wasathiyyah (moderation) in maintaining tolerance, and the absolute integration of faith with social morality. To be effective, these values must be institutionalized within Islamic education through the transformation of critical pedagogy, the strengthening of religious digital literacy, and the development of an inclusive school culture. Strengthening aqidah is therefore not merely a transfer of dogma, but the formation of a moderate worldview as a strong shield against the infiltration of radical ideologies.

The development of Artificial Intelligence (AI) technology has created various digital innovations, but it has also generated new forms of crime through the misuse of deepfake technology. This study aims to analyze the legal liability of social media platforms for the dissemination of AI-based deepfake content and the forms of legal protection for victims of digital fraud, particularly elderly groups, in the case of the “magical money ritual” scam using the identity of Ujang Busthomi.

Students’ low critical thinking skills in mathematics remain a persistent issue, largely due to teacher-centered instructional practices that limit student participation and hinder deep conceptual understanding. To address this problem, a more engaging learning approach is required, such as the Student Teams Achievement Divisions (STAD) cooperative learning model. This study aims to examine whether students taught using the STAD model demonstrate higher critical thinking abilities than those taught through direct instruction in social arithmetic topics. The research employed an experimental method with a quantitative approach, using a posttest-only control group design. The sample consisted of two classes: an experimental group and a control group. Data were collected through essay-based tests designed to measure students’ critical thinking skills. The analysis involved prerequisite testing and hypothesis testing using an independent sample t-test. The findings revealed that the calculated t-value (2.033) exceeded the t-table value (2.00958) at a 0.05 significance level, indicating a significant difference. Therefore, the STAD model proves more effective in enhancing students’ critical thinking skills.
